Difficulty: EasyRelief and Major Landforms of Africa

Which of the following major African landforms is an extensive high plateau formed primarily by basaltic volcanic activity?

  1. The Ethiopian HighlandsAnswer
  2. B
    The Congo Basin
  3. C
    The Nile Delta
  4. D
    The Sahara Erg Regions

Answer

The Ethiopian Highlands
The Ethiopian Highlands were created by extensive fissure eruptions of basaltic lava during the Tertiary period, producing a vast, elevated volcanic plateau often called the 'Roof of Africa'.

Step-by-Step Solution

1
Analyze the landform description provided in the question stem.
The target landform must be an elevated plateau of volcanic origin.
The question specifies both the physical structure (high plateau) and the formation mechanism (volcanic activity).
2
Evaluate the relief features of Africa against this geological origin.
The Ethiopian Highlands were formed by massive flood basalt lava outpourings associated with rift system development.
This physical region is widely recognized as Africa's largest continuous high-altitude volcanic plateau structure.
